RX 570 Adrenalin: Frequent Green Screen despite latest software

I read through several "green screen" posts here and I did not find a solution to my problem:

I had a monitor flickering once in a while, two days ago it started switching to solid green. After examining cables, connections and switching monitors, I updated the driver, and everything was ok.

Next day, the same story. On top of it, the 2nd monitor showed disconnected. To my surprise, I was able to update the driver again. I also switched to another display port outlet (primary HDMI works fine).

This morning it happened again and I downloaded completely new software package, latest release.

While it improved considerably, the green screen is still occurring like three times an hour for a second.

I just tried it out myself, got the green static-green screen loop. I'm switching back to the 17.7.2 drivers. They are the only ones I don't have this issue with. What stinks is I did see a little improvement gameplay wise, but not enough to justify putting up with the static issues. Seriously, AMD needs to fix this before releasing new drivers. I've had the issue since the 17.9 driver set.
